Application filed November 4To all 107mm t may concern:

` Re it known that 1, Hanni' Brenn, a citi zen ot the United States, residing at o.

371A West 46th Street, New York, in the county of New York, State of New York, have invented certain new and useful 1inprovements in Spinning Machines; and 1 do hereby declare the following to be a full, clear, and exact description oit' the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

rlhis invention relates to spinningl niachines of the type disclosed in my lfatent No. 1,113,489 of October 13, 1914.

rltlie spinning machine disclosed in my prior patent, is adapted to be used for the vpurposeot spinning` yarn, and, more pai'- tioularly, tor spinning fibres around a iviie core, thus forming a Wire fibrous yarn. The

. fibres are spun around the Wire in such a mannerthat they are all parallel to each other, and therefore adapted to carry an equal stress when the yarn is under tension.

rlie present invention relates to improve- Vments in spinning' machines ot this type,

. he made.

y lates especially to the apparatus tor eedin'" whereby a multiple Wire fibrous yarirniay I rlhis multiple Wire fibrous yarn, which forms the subject matter of my co pending application, Serial No. (503,993 filed November 29, 1922, has a core formed of a plurality of single wire fibrous yarns ot the type made on the machine disclosed iu my prior patent". This core may be said to consist of a plurality ot parallel yarns and the express-ion parallel yarns, is intended to designate yarns that are not in intertwined relation.V This core is covered ivi-th fibres spun around it in the same manner that the fibres were spun around the single Wire core of the yarn made by `my original machine. More particularly, the present invention rea plurality ot Wires, or single wire fibroi yarns, to the conveyor of the spinning' machine. By means of the present invention,

it is possible to supply a i'plurality ot ivire or Wire fibrous yarns to the flier ot the spinning machine in such a manner that the groupof Wire fibrous yarns revolve as a While at the same speed as tlieitlier ot the spinning machine, While the individual Wire a9, 1922. sensi no. 603,992.

tibrous yarns, lyingv parallel to each other, enter the iiippei without being subjected to torsion or twist and are spun into a single yarn the saine as a single wire is spun into a single fibrous yarn as disclosed in my 'prior patent. Thus it is possible to make a multiple uire fibrous yarn havinga core consisting ot a plurality ot u'ire fibrous yarns parallel with each other, the core being made in such a manner that there is no torsional stress in the elements forming the core.

rThe principal object ol the present iiivention is attained by providinga spool holder adapted to hold a plurality oi spools from which single Wire fibrous yarns, or wires, may be supplied, the spool holder bein@` arranged in such a manner that it may rotate about an axis at substantially right angles to the axes ot the several spools. Each of the spools is rotated in the direction opposite to that in which the spool holder rotates, the mechanism tor producing,l this motion consisting` of a eccentrically mounted Wrist plate connected to the several spools by means ot cranhs or other equivalent means. Thus the group ot yarns taken troni the spools may be rotated as a whole by rotating the spool `holder and each .individual yarn is prevented from twisting' as the spool holder revolves, by means ot the Wrist plate which causes the spools to rotate with respect to the spool holder, in the direction opposite to the direction ot rotation ot the spool holder.

The present invention may be best understood by referringl to the following detailed description which is to be considered in conjunction with the accompanying drawings, in ivhichw Figi'. 1 is an elevation of a piece of single Wire fibrous yarn as made by the spinning machine disclosed in my prior Patent No. 1,113,439.

Fig. 9 is a rdetailed. drawing of a form of tensioning device which may be used in conjunction with the spools on the spool holder.

By referring to Figs. and 7 of the drawings, it may be noted that the improved spinning machine is similar in many respects to that disclosed in my Patent No. 1,113,4t89.' The machine is provided with a trumpet 52 for supplying fibres to the conveyor 51, the fibres being` deposited on the conveyor51 parallel to each other andrto the direction of movement of' the conveyor. The fibres pass along the conveyor to the nipper rolls 16 and 50. ln my prior patent a single Wire is passed along thetop or the conveyor 51, whereas in the present invention a plurality of wire fibrous yarns are passed along the top of this conveyor. The yarns pass throughs groove in the upper nipper roll 16 and over the divider 17. rlhe v libres pass under theV divider 17 and both the yarns and. fibres enter the rotating sleeve 18 which spins the fibres around the yarns, thus forming a multiple Wire fibrous yarn havinp` a core consisting` of a plurality of single Wire fibrous yarns around which the` libres Y from the conveyor have been spun in such shaft 5.

a manner that they all lie parallel to each other. As the finished yarn passes from the sleeve 18 it passes around capstan sheaves 19 and around guide sheaves 2() and onto the spool 21.

r1`he ,raw fibres may be supplied to the trumpet 52 in the usual manner, and the conveyor' 51, on which the fibres are deposited, may be driven in any suitable manner, for example, by means of the* gears 8O and 31 which are driven by the sheave 29 which is, in turn, driven from the main drive shaft 2.` The rotating sleeve 18 mayV be driven by means of a suitable gear train 86 Which may also drive the capstan sheaves 19, as best shown in Fig. 6.

rlhe flier 8 is caused to rotate by means ot gears 6, 9 and 7, gear 7 being rigidly connected to the flier 8, gear 6 being connected to the shaft 5, and gearl 9 serving as an idler. The spool holder 12, which will be described later, is caused to rotate in synchronism With flier 8 by means of suitable gears 11 and 13, the latter gear being fixed to Vthe The spool 21, Von which the finished yarn is Wound, is fastened'to a hollow shaft 23 which is loosely Wound on a rod 22. This spool 21 is caused to rotate by means of gears 24, 25 and 26. Gear 26 is rigidly fastened to the sleeve 23, and gear 241 is driven byfriction Contact with gear 6, the

the machine, the details of the spool holder( mechanism may now be considered. As mentioned above, the spool holder 12 ro` tates in the same direction and With the same speed thatV the flier 8 rotates. The spool holder 12 comprises a disc or other suitable support, on which a plurality of' spools 141 are mounted. The yarns pass from the several spools to a suitable ring 35 for the purpose of bringing the yarns together to form a substantially compact core which passes along abovethe conveyor 51 in the manner described above.

lt is an established fact that it a Wire or yarn of any description is grasped firmly and unwound from a spool by pulling` the wire'or yarn straight away from the spool' the Wire or yarn is subjected to considerable torsion. The direction of this torsion de-V pends upon whether the wire or yarn is taken from the underside of the spool or from the top. ln'order to relieve the Wire or yarn from this torsion, it is necessary to either turn the spool from which the Wire or yarn is taken, or to turn the Wire itself. ln either case this turning should be in such a direction that it tends to take the torsion or twist out of the Wire or yarn.

1f the spools 14e were Vrigid on the spool holder, a considerable torsion or twist would be developed in each yarn when it is drawn from its spool. Thus, if the machine Was constructed in this Way, each yarn of the core would tend to turn about its own aXis as the core was caused to rotate about its axis. ln order to eliminate or neutralize this torsion it is necessary to rotate each of the spools 14 in the direction opposite to that in which the spool holder'rotates. rlhis is accomplished byrmeans of the Wrist plate 1Q "rhich is rotatively mounted on a fixed support 60. This support 60 is arranged in such a ivay that the Wrist plate 10v isv eccentrically mounted with respect to the axis of the spool holder.vv The Wrist plate 10 is connected to the spools on the spool holder byl means of cranks 61, the length oit' each crank beingequal to the eccentricity of the support 60. The Wrist plate 10 rotates With the spool holder and as these tivo members rotate together, the spools are lcaused to rotate in the opposite direction by virtue of the cranks 6l interconnecting the spools and the Wrist plate.

The tensioning device shown in Fig. 9 consists ot a guide roller or sheave G2 rotatably mounted on links G3 which are piv oted at the outer extremities thereof. The yarn 'troni the spool 14 passes around the guide sheare (52, and the pressurel of the sheaye on the spool is automatically adjusted by the tension in the yarn. The object of this device is to prevent the yarns troni unu'inding` troni the spools too rapidly.

Freni the above description it should be apparent that a nniltipie `rire fibrous yarn may be niade by using' a plurality of single wire fibrous yarns of the type shown in Fig. l. Thel yarn of Fig. l consists of a Wire core around which fibres 6G have been spun in such a manner that they lie parallel to each other. The inultiple Wire fibrous yarn as shown in Fie'. 3 consists ot a core 67 composed o'l'f a plurality ot single Wire fibrous yarns as shown in Fig'. l, and a coveringvof fibres G6 spun around the core in the saine inanner that the bres are spun around the wire core ot' the single Wire fibrous yarn.

While I prefer to inake the multiple wire fibrous yarn by using a. plurality of single Wire fibrous yarns as a core, it is to be understoot that such a multiple yarn may be niade by using' a plurality of bare Wires for the core, and when it is stated that a ineans is provide-d for supplying a plurality of yarns to the conveyor ot' the machine, it is to be understood that this ineans niay be used for the purpose of feeding a plurality of bare Wires. I prefer to inalre multiple Wire fibrous yarns by using' a plurality of single wire fibrous yarns as a core instead ot bare Wires tor the reason that the libres around the single Wire iibrous yarn prevent the cnclosed wires from chafing` against each other and thus wearing` out the multiple yarn. rihe inultiple Wire fibrous yarn having' single Wire fibrous yarns for a core forins aflexible yarn in which the Wires may carry a large part of any load applied to the yarn, and in which the Wires are prevented frein wearing against each other,

It is also to be understood thatl the size, proportions and arrangement of the various parts may be varied Without departing troni the spirit et the invention which is not confined to the particular einbodiinent shown and described but is intended to include such modifications thereot as fall Within the scope of the appended claiins.

l. In a machine of the type described,

Ineans for feeding straight fibres, a spoolholder adapted to hold a plurality ot spools for feeding' yarns, ineans for rotating said spool-holder, ineans cooperating with said spooldiolder to forni a core et' parallel yarns, ineens for preventing the yarns troni turnin;n about their respect-ive axes when the spool-holder revolves., and nieans for spin ning said fibres parallel to each other spirally around said yarns.

2. In a machine ot' the type described, a rotatably mounted spool-holder adapted to hold a plurality ot' Spools for feeding' yarns, a wrist plaie rotatably mounted Ona fixed supporti eccentric with respect to the axis of said spool-holder, ineans ior interconnectingY said u'rist plate and the spools whereby the itl st plate may cause the spools to rotate in one direction about their transverse axes 'while the spool-holder rotates in the opposi direction, a flier arranged to rotate in the saine direction and With the saine speed that the spool-holder rotates, whereby a core et parallel yarns is termed, ineans for feedstraight fibres and nieans for spinningl straight fibres parallel to each other' spirally around said core.

o. The method ot makina* a rope structure, which consists in feeding,- yarns from a plurality ot spools in such a manner that there no torsion in the yarns, drai'ving the yarns together to 'forni a core of parallel yarns, and spinning fibres around said core.

6. rI`he method of making a rope structure, which consists in feeding yarns from a plurality of spools niounted in a spool holder. drawing` the yarns together to forni a core et parallel yarns, rotating said spool holder to rota-te said core, rotating' each of said spools so that there is no torsion in the yarns :ted therefrom, and spinningl libres around said rotating' core.

In testimony whereof I allix niy signature.
